These coil springs are of the same size anclform as the spmngs G and g, aDdOQQEQf s recess p.

Considering Figs- 5 and 6, the front wheel 7c is shown conne'cteiiijwith thefpivotal steering knuckle S providedwith the usual arm 8 by-which it may be coupled to suitable gear for-steering the vehicle. ;Therrider T slightly modified in form'to properly receive the jst'eeringlrnuckle'and the "fork oi the 4 i. front ,axle j." "The rider T seatsthe upper coil springs U and a,- and thelower' coil springs V and o, havingse'ats for thatpurpose as described in explaining. the con- I structionof the rider a, and the bolts W and wjtl1rough the rider and the coil springs.

"lconnect the ends oat-the springs with the ficrosshe'ads E and P. The bolts W and i0 are-duplicates of the bolt 0 shown in'Fig. -1

. I passing'throughthe rider a and the upper and lower coil springs G and N. I j v In explaining the operation of this inventi'on, attention is invited to the'fact'that the vertical bolts 0, W and wthatfpass Lao-through the riders and coil springs have ,shouldered ends as'illustrated in Fig, 1, and the 'crossheads n, E, P, fare rigidly clamped upon the ends of the bolts. A downward m'oveinentof the frame or body A ot'the 3,5 vehicle would, therefore, compress coil spr1ngs'G and g,' an'd their fellows on the o other end of the axle, and the movement would alsobend the leaf springs and R. -v @It will be'noted that a, considerable por- I 4ogtion-of the load in the operation of this invention is carried by the -middle of the fiaxle'J, and the remainder of the weight is divided between theriders at the ends of "'the axle 1 5 It is believed to-be clear from the forev oing description and the illustration in ,ig, 1, that any rocking movement ofthe vehicle'eng'ages all the springs both coiland leaf, aflording ample cushioning effect.

Furthermore, assuming that the wheels should'suddenly meet with an obstacle compellingthem to rise abruptly, the upward movement of "the axle would be taken up by. the lower coil springs and both leaf 55 springs and any unpleasant 'efi'ect' mitigated v materially. v

This invention is not limited to any nu1'n 7 her of'coil springs or. leafsprings, but is intended rather to increase, the number of Su -springs beyond", the-number usually em- I '"z ployed' with the'viewioflproducing a corres ending agreeable cushioning 1 result for "the occuparits of the vehicle. how described this invention and one of the cross-heads, and the other end Iclaim is g '1.
